Strategies for prompt searches for GRB afterglows: the discovery of the GRB 001011 optical/near-infrared counterpart using colour-colour selection
J. Gorosabel, J. U. Fynbo, J. Hjorth +25
We report the discovery of the optical and near-infrared counterparts to GRB 001011. The GRB 001011 error box determined by Beppo-SAX was simultaneously imaged in the near-infrared…
X-ray and optical monitoring of the peculiar source 4U 1700+24/V934 Her
N. Masetti, D. Dal Fiume, G. Cusumano +10
(Abridged) We report on ASCA and BeppoSAX observations of the X-ray source 4U 1700+24 and on (quasi-)simultaneous spectroscopy of its optical counterpart, V934 Her, from the Loiano…
BeppoSAX view of NGC 526A: a Seyfert 1.9 galaxy with a flat spectrum
R. Landi, L. Bassani, G. Malaguti +8
In the present work we report the BeppoSAX observation of the Seyfert 1.9 galaxy NGC 526A in the band 0.1-150 keV. The high energy instrument onboard, PDS, has succeeded in measuri…
The bright optical afterglow of the long GRB 001007
J. M. Castro Cerón, A. J. Castro-Tirado, J. Gorosabel +35
We present optical follow up observations of the long GRB 001007 between 6.14 hours and ~468 days after the event. An unusually bright optical afterglow (OA) was seen to decline fo…
REM Optical Slitless Spectrograph (ROSS): an instrument for prompt low resolution spectroscopy of Gamma Ray Bursts
Eliana Palazzi, Elena Pian
Since the discovery of Gamma-Ray Bursts (GRBs), attempts have been made to detect correlated optical transient emission from these objects. In January 1999, the ROTSE I robotic tel…
A measurement of the broad-band spectrum of XTE J1118+480 with BeppoSAX and its astrophysical implications
F. Frontera, A. A. Zdziarski, L. Amati +12
We report on results of a target of opportunity observation of the X-ray transient XTE J1118+480 performed on 2000 April 14-15 with the Narrow Field Instruments (0.1-200 keV) of th…
